Who can you turn to when everyone betrays your trust? This is an especially important question for Ruth Gallagher. Severely injured at the same time that her best friend is killed in a mountain climbing incident, she later learns it was no accident. Repeated attempts on her life are made when a mobster believes she knows more about his criminal enterprises than she does.

Riding to the rescue is U.S. Marshal Emma Blake, but after all the perfidy can Ruth trust Emma? Barely healed from her previous encounters, she may not have a choice.
